Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Fungus
  • Ecology

Krishnapillai Sivasithamparam mainly focuses on Botany, Microbiology, Agronomy, Germination and Trichoderma. His research ties Horticulture and Botany together. His Horticulture research is multidisciplinary, incorporating perspectives in Transpiration and Stomatal conductance.

His work on Fungi imperfecti and Pathogen as part of general Microbiology study is frequently linked to Antagonism, therefore connecting diverse disciplines of science. When carried out as part of a general Germination research project, his work on Dormancy is frequently linked to work in Caladenia, therefore connecting diverse disciplines of study. His studies deal with areas such as Botrytis cinerea, Elicitor and Leptosphaeria maculans as well as Trichoderma.

His most cited work include:

  • Trichoderma–plant–pathogen interactions (702 citations)
  • A novel role for Trichoderma secondary metabolites in the interactions with plants (308 citations)
  • Biological control of Sclerotinia minor using a chitinolytic bacterium and actinomycetes (206 citations)

What are the main themes of his work throughout his whole career to date?

Krishnapillai Sivasithamparam focuses on Botany, Agronomy, Horticulture, Microbiology and Root rot. His research on Botany often connects related topics like Inoculation. His work on Agronomy is being expanded to include thematically relevant topics such as Soil water.

His work in the fields of Horticulture, such as Cultivar, Plant breeding and Shoot, intersects with other areas such as Lime. The Pathogen research Krishnapillai Sivasithamparam does as part of his general Microbiology study is frequently linked to other disciplines of science, such as Antagonism, therefore creating a link between diverse domains of science. His Rhizoctonia solani research includes themes of Pythium irregulare and Fungi imperfecti.

He most often published in these fields:

  • Botany (53.30%)
  • Agronomy (26.93%)
  • Horticulture (22.64%)

What were the highlights of his more recent work (between 2006-2021)?

  • Botany (53.30%)
  • Brassica (9.46%)
  • Agronomy (26.93%)

In recent papers he was focusing on the following fields of study:

His primary areas of investigation include Botany, Brassica, Agronomy, Horticulture and Plant disease resistance. His Botany research includes elements of Pathogen and Host. The various areas that Krishnapillai Sivasithamparam examines in his Brassica study include Canola, Inoculation, Sclerotinia and Germplasm.

His Horticulture research incorporates elements of Oomycete and Crop. His biological study spans a wide range of topics, including Veterinary medicine, Biotechnology, Trichoderma and Biological pest control. The Trichoderma study combines topics in areas such as Botrytis cinerea, Trichoderma harzianum, Nutrient and Elicitor.

Between 2006 and 2021, his most popular works were:

  • Trichoderma–plant–pathogen interactions (702 citations)
  • A novel role for Trichoderma secondary metabolites in the interactions with plants (308 citations)
  • Plant growth promotion and biological control of Pythium aphanidermatum, a pathogen of cucumber, by endophytic actinomycetes. (151 citations)

In his most recent research, the most cited papers focused on:

  • Botany
  • Fungus
  • Ecology

The scientist’s investigation covers issues in Botany, Brassica, Sclerotinia sclerotiorum, Plant disease resistance and Horticulture. His studies in Botany integrate themes in fields like Pathogen and Host. His Brassica study combines topics from a wide range of disciplines, such as Canola and Germplasm.

His Sclerotinia sclerotiorum research also works with subjects such as

  • Sclerotinia together with Stem rot,
  • Cotyledon together with Microbiology, Metabolic pathway, Protein biosynthesis, Pathosystem and Palisade cell. His Plant disease resistance course of study focuses on Agronomy and Fusarium oxysporum and Phytophthora cactorum. In his study, Virulence and Crown is inextricably linked to Oomycete, which falls within the broad field of Horticulture.
